Java – how to check whether the element in the int array is empty?

Example:

I want to see if array [5] saves a value or is empty

Solution

Elements in the original array cannot be empty They are always initialized to something (usually 0, for int arrays, but depending on how you declare the array)

If you declare an array like this (for example):

int [] myArray ;
myArray = new int[7] ;

Then all elements will default to 0

The alternative syntax for declaring arrays is

int[] myArray = { 12,7,32,15,113,7 };

The initial value of the array (size 7 in this case) is given in braces {}
